Bool and Hacks Lagoons are freshwater wetlands that comprise a number of semi-permanent lagoons characterised by shallow, circular swamps and creeks.
The site has an area of 3,200 hectares and is designated as a game reserve (Bool Lagoon) and conservation park (Hacks Lagoon). The wetlands act as a buffer storage basin in the regional drainage system and provide significant breeding habitat and drought refuge for waterbirds.
This Ramsar site is one of the most important wetland areas remaining in the southeast of South Australia and contains important examples of plant diversity.
It is a wetland of national importance for colonial nesting birds and hosts the largest ibis rookery in South Australia. In total, 79 species of waterbirds have been recorded in the area, including the state vulnerable Australasian bittern (Botaurus poiciloptilus) and freckled duck (Stictonetta naevosa).
